Hi,
i'm trying to setup a toolchain file for cross-compilation with target specfic
options and afaics cmake dosen't use flags from such file:
$ cat CMakeLists.txt
cmake_minimum_required( VERSION 2.8.7 )
project( test CXX )
add_executable( main main.cpp )
$ cat CMakeToolchain-x86_64-gnu-linux.txt
set( CMAKE_SYSTEM_NAME Linux )
set( CMAKE_SYSTEM_VERSION 1 )
set( CMAKE_CXX_COMPILER
/local/devel/toolchain46/x86_64-gnu-linux/bin/x86_64-gnu-linux-g++ )
set( CMAKE_CXX_FLAGS "-Wall -O1 -gdwarf-4 -g2 -std=gnu++0x" )
set( CMAKE_FIND_ROOT_PATH /usr )
$ LANG=C sh -x ./build.sh
+ rm -rf build
+ mkdir build
+ cd build
+ cmake ../ -DCMAKE_TOOLCHAIN_FILE=../CMakeToolchain-x86_64-gnu-linux.txt
-- The CXX compiler identification is GNU

[100%] Building CXX object CMakeFiles/main.dir/main.cpp.o
/local/devel/toolchain46/x86_64-gnu-linux/bin/x86_64-gnu-linux-g++ -o
CMakeFiles/main.dir/main.cpp.o -c
/home/users/pluto/src/cmake-cross-build/main.cpp
^^^ no cxx
flags.
is it a bug or a feature?
BR,
Paweł.
