[CMake] problem using a new toolchain

[Daniel Franzini]

hi

I'm trying to create a CMake build environment for a medium sized
application. The application is getting ported to several plataforms and I
would like to have just one build environment.

The host plataform is WinVista/Linux. The first target plataform I'm trying
to create a build for is PSP. PSP have a toolchain (PSPSDK) which is based
in GNU tools. I'm trying to write a new toolchain file for using the PSPSDK.

-----------------------------PSPSDK-Toolchain.cmake-----------------------------
# the name of the host operating system
SET(CMAKE_SYSTEM_NAME "Generic")

# here the target toolchain is located for cross compilation
SET( CMAKE_FIND_ROOT_PATH "C:\\pspsdk\\bin" )

# which compilers to use for C and C++
SET( CMAKE_C_COMPILER psp-gcc )
SET( CMAKE_CXX_COMPILER psp-g++ )
SET( CMAKE_MAKE_PROGRAM make )
SET( CMAKE_RC_COMPILER psp-ar )
-----------------------------PSPSDK-Toolchain.cmake-----------------------------

It seems that CMake can find the psp-gcc and psp-g++ but the configure
process fails because it cannot find some basic libraries needed.

The log of the configure process is:

----------------------------------------------------------------------------------------------
The C compiler identification is GNU

The CXX compiler identification is GNU

The C compiler "C:/pspsdk/bin/psp-gcc.exe" is not able to compile a simple

test program.

 It fails with the following output:

 Configuring incomplete, errors occurred!
----------------------------------------------------------------------------------------------

It is clear that it can find the compiler but cannot find the
libraries...some are common C functions (strlen, etc); other are PSP
specific (sceKernelCreateThread, etc). How can I ask CMake to link some
libraries to every executable which is using this particular toolchain? Will
I have to manually set in CMakeLists.txt


Also, it is using the wrong make.exe program (is there a variable where I
can force it to use a specific make)?
