# Author: Micah Snyder
# To see this in a sample project, visit: https://github.com/micahsnyder/cmake-rust-demo
#
# Code to set the Cargo arguments was lifted from:
# https://github.com/Devolutions/CMakeRust
#
# This Module defines the following variables:
# - <program>_FOUND - True if the program was found
# - <program>_EXECUTABLE - path of the program
# - <program>_VERSION - version number of the program
#
# ... for the following Rust toolchain programs:
# - cargo
# - rustc
# - rustup
# - rust-gdb
# - rust-lldb
# - rustdoc
# - rustfmt
# - bindgen
#
# Callers can make any program mandatory by setting `<program>_REQUIRED` before
# the call to `find_package(Rust)`
#
# Eg:
# find_package(Rust REQUIRED)
#
# This module provides the following functions:
# =============================================
#
# `add_rust_library()`
# --------------------
#
# This allows a caller to create a Rust static library
# target which you can link to with `target_link_libraries()`.
#
# Your Rust static library target will itself depend on the native static libs
# you get from `rustc --crate-type staticlib --print=native-static-libs /dev/null`
#
# The CARGO_CMD environment variable will be set to "BUILD" so you can tell
# it's not building the unit tests inside your (optional) `build.rs` file.
#
# Example `add_rust_library()` usage:
#
# ```cmake
# add_rust_library(TARGET yourlib
# SOURCE_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}")
# BINARY_DIRECTORY "${CMAKE_BINARY_DIR}")
# add_library(YourProject::yourlib ALIAS yourlib)
#
# add_executable(yourexe)
# target_link_libraries(yourexe YourProject::yourlib)
# ```
#
# If your library has unit tests AND your library does NOT depend on your C
# librar(ies), you can use `add_rust_library()` to build your library and unit
# tests at the same time. Just pass `PRECOMPILE_TESTS TRUE` to add_rust_library.
# This should make it so when you run the tests, they don't have to compile
# during the test run.
#
# If your library does have C dependencies, you can still precompile the tests
# by passing `PRECOMPILE_TESTS TRUE`, with `add_rust_test()` instead.
# It will be slower because it will have to compile the C stuff first,
# then compile the Rust stuff from scratch. See below.
#
# `add_rust_test()`
# -----------------
#
# This allows a caller to run `cargo test` for a specific Rust target as a CTest
# test.
#
# The CARGO_CMD environment variable will be set to "TEST" so you can tell
# it's not building the unit tests inside your (optional) `build.rs` file.
#
# Example `add_rust_test()` usage:
#
# ```cmake
# add_rust_test(NAME yourlib
# SOURCE_DIRECTORY "${CMAKE_SOURCE_DIR}/path/to/yourlib"
# BINARY_DIRECTORY "${CMAKE_BINARY_DIR}"
# )
# set_property(TEST yourlib PROPERTY ENVIRONMENT ${ENVIRONMENT})
# ```
#
# Experimental: Precompile the Tests Executable
# ~~~~~~~~~~~~
# This feature will cause install failures if you `sudo make install` because
# it will recompile the test executable with sudo and Cargo is likely to fail to
# run with sudo.
# This cannot be fixed unless we can predetermine the test exeecutable OUTPUT
# filepath. See: https://github.com/rust-lang/cargo/issues/1924
#
# If your library has unit tests AND your library DOES depend on your C
# libraries, you can precompile the unit tests application with some extra
# parameters to `add_rust_test()`:
# - `PRECOMPILE_TESTS TRUE`
# - `PRECOMPILE_DEPENDS <the CMake target name for your C library dependency>`
# - `PRECOMPILE_ENVIRONMENT <a linked list of environment vars to build the Rust lib>`
#
# The `PRECOMPILE_DEPENDS` option is required so CMake will build the C library first.
# The `PRECOMPILE_ENVIRONMENT` option is required for use in your `build.rs` file so you
# can tell rustc how to link to your C library.
#
# For example:
#
# ```cmake
# add_rust_test(NAME yourlib
# SOURCE_DIRECTORY "${CMAKE_SOURCE_DIR}/yourlib"
# BINARY_DIRECTORY "${CMAKE_BINARY_DIR}"
# PRECOMPILE_TESTS TRUE
# PRECOMPILE_DEPENDS ClamAV::libclamav
# PRECOMPILE_ENVIRONMENT "${ENVIRONMENT}"
# )
# set_property(TEST yourlib PROPERTY ENVIRONMENT ${ENVIRONMENT})
# ```
#
# `add_rust_executable()`
# -----------------------
#
# This allows a caller to create a Rust executable target.
#
# Example `add_rust_executable()` usage:
#
# ```cmake
# add_rust_executable(TARGET yourexe
# SOURCE_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}"
# BINARY_DIRECTORY "${CMAKE_BINARY_DIR}"
# )
# add_executable(YourProject::yourexe ALIAS yourexe)
# ```
