Summary: -DCMAKE_BUILD_TYPE silently ignored if specified
together with -DCMAKE_CXX_COMPILER
Description:
Hello,
The commands listed below exemplify that one may get different behaviour of
CMake when running:
cmake . -DCMAKE_CXX_COMPILER=g++-4.7 -DCMAKE_BUILD_TYPE=Release
and
cmake . -DCMAKE_CXX_COMPILER=g++-4.7;
cmake . -DCMAKE_BUILD_TYPE=Release
HTH,
Sylwester
Steps to Reproduce:
$ cat CMakeLists.txt
project(test CXX)
set(CMAKE_CXX_FLAGS_RELEASE "-Ofaast")
add_executable(test test.cpp)
$ cat test.cpp
int main() {}
$ cmake . -DCMAKE_CXX_COMPILER=g++-4.7 -DCMAKE_BUILD_TYPE=Release
