Summary: "The CMAKE_C_COMPILER … is not a full path and was
not found in the PATH" if using CMakeDetermineSystem and toolchain file
Description:
There is an issue that prevents any version of freerdp to build on Gentoo using
CMake 3.0.2.
At first, Gentoo's portage passes -DCMAKE_TOOLCHAIN_FILE=gentoo_toolchain.cmake
to cmake command line; gentoo_toolchain.cmake contains following:
SET (CMAKE_C_COMPILER x86_64-pc-linux-gnu-gcc)
SET (CMAKE_CXX_COMPILER x86_64-pc-linux-gnu-g++)
And when I try to build freerdp, the following message from CMake appears:
cmake --no-warn-unused-cli -C

CMake Error at winpr/CMakeLists.txt:20 (project):
The CMAKE_C_COMPILER:
x86_64-pc-linux-gnu-gcc
is not a full path and was not found in the PATH.
Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.
I tried to reproduce the bug with minimal CMakeLists.txt. The bug can be
reproduced with the following script:
mkdir src
cat > CMakeLists.txt << "EOF"
cmake_minimum_required(VERSION 3.0.2)
project(test C)
include(CMakeDetermineSystem)
add_subdirectory(src)
EOF
cat > src/CMakeLists.txt << "EOF"
cmake_minimum_required(VERSION 3.0.2)
project(src C)
EOF
cat > toolchain.cmake << "EOF"
set(CMAKE_C_COMPILER x86_64-pc-linux-gnu-gcc)
EOF
cmake . -DCMAKE_TOOLCHAIN_FILE=toolchain.cmake
You will see the following output:
-- The C compiler identification is GNU 4.9.2
-- Check for working C compiler: /usr/bin/x86_64-pc-linux-gnu-gcc
-- Check for working C compiler: /usr/bin/x86_64-pc-linux-gnu-gcc -- works

CMake Error at src/CMakeLists.txt:2 (project):
The CMAKE_C_COMPILER:
x86_64-pc-linux-gnu-gcc
is not a full path and was not found in the PATH.
Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.
-- Configuring incomplete, errors occurred!
See also "/tmp/test/CMakeFiles/CMakeOutput.log".
I think that the reason of the bug is that CMake sets
CMAKE_C_COMPILER=/usr/bin/x86_64-pc-linux-gnu-gcc after parsing toolchain file,
but CMakeDetermineSystem module includes toolchain file again, and now
CMAKE_C_COMPILER=x86_64-pc-linux-gnu-gcc, which leads to failure.
Steps to Reproduce:
Look at script above.
