[CMake] CHECK_FUNCTION_EXISTS(UuidCreate HAVE_UUIDCREATE)

[Mathieu Malaterre]

Hi,

  According to:

http://msdn.microsoft.com/en-us/library/aa379205(VS.85).aspx

  The symbol UuidCreate can be found in rpcrt4, so I used the
following cmake commands:


SET(CMAKE_REQUIRED_LIBRARIES "rpcrt4")
CHECK_FUNCTION_EXISTS(UuidCreate HAVE_UUIDCREATE)

  But running it, gives me:

-- Looking for UuidCreate
-- Looking for UuidCreate - not found

And in the log:


Determining if the function UuidCreate exists failed with the following output:
        nmake -f CMakeFiles\cmTryCompileExec.dir/build.make /nologo -L
                 CMakeFiles\cmTryCompileExec.dir\build^M

Of course, if I manually force the linking to rpcrt4 everything works
as expected...

Anyone sees my mistake ?

Thanks,
