Thanks - that worked nicely.

Now I have another problem. I need to link to the Python libraries. So I specify:

FIND_PACKAGE(PythonLibs REQUIRED)
INCLUDE_DIRECTORIES(${PYTHON_INCLUDE_PATH})

<snip>

message (${PYTHON_LIBRARY})
add_library( Kernel STATIC ${SRCS} )
TARGET_LINK_LIBRARIES(Kernel ${PYTHON_LIBRARY})

The message shows:

/usr/lib64/libpython2.4.so

but this path does not appear in the link command so the build fails.

I am trying to build a static library so am worried why ${PYTHON_LIBRARY} is a shared library.

By the way, is it normal CMake style to write CMAKE commands in upper or lower case?

Can you help with these questions please?

BR
