[CMake] CMake Error: Attempt at a recursive or nested TRY_COMPILE in directory

[Bernd Schubert]

Hi, 

I'm just beginning to learn CMake and now I'm lost.

I need to check for large file support and therefore need to use TRY_COMPILE. 
In my main CMakeLists.txt file I tried similar to my Mastering CMake book 
(for version 2.0):

TRY_COMPILE(C_MAKE_COMPILER_WORKS
            ${CMAKE_BINARY_DIR}
            ${PROJECT_SOURCE_DIR}/CMake_Modules/Test_64_Bit_Offset.c
            OUTPUT_VARIABLE_OUTPUT)

bernd at bathl funionfs-0.4>cmake .
CMake Error: Attempt at a recursive or nested TRY_COMPILE in 
directory /home/bernd/src/funionfs-0.4
-- Configuring done

Should this TRY_COMPILE go into another CMakeLists.txt file in a subdir? But 
how would I get the result in the main config file then?

Thanks,
	Bernd

PS: I guess tests for large file support should happen rather often, so 
shouldn't this added to the available modules?
