Hello all,
On linux, what's the correct way to support building with several different C
compilers, each with some extra compiler-specifc flags for Debug and Release
modes? (Eventually I'll need to add Visual Studio on Windows too. )
For now, I'm following what's mentioned in the cmake FAQ and using CXX=/blah
cmake, etc.
(From: https://cmake.org/Wiki/CMake_FAQ#How_do_I_use_a_different_compiler.3F)
But this is getting quite cumbersome as I'm experimenting with different flags
for each compiler, and I'd rather avoid polluting my fairly clean CMakeLists
file with a bunch of if/else branches to set flags.
In the cmake manual I see reference to a -DCMAKE_TOOLCHAIN_FILE option, but
this seems designed for embedded cross-compile scenarios. (Is that right?)
(From: https://cmake.org/cmake/help/v3.0/manual/cmake-toolchains.7.html)
Basically, I'd like to succinctly choose among a set of (slightly) customized
compiler choices.
For modern cmake usage what is the correct method? Can anybody point me to a
well done example for a simple case like this?
Thank you!
tcw
