Boost python linking

I'm adding boost.python for my Game. I write wrappers for my classes to use them in scripts. The problem is linking that library to my app. I'm using cmake build system.

Now I have a simple app with 1 file and makefile for it:

PYTHON = /usr/include/python2.7

BOOST_INC = /usr/include
BOOST_LIB = /usr/lib

TARGET = main

$(TARGET).so: $(TARGET).o
    g++ -shared -Wl,--export-dynamic \
    $(TARGET).o -L$(BOOST_LIB) -lboost_python \
    -L/usr/lib/python2.7/config -lpython2.7 \
    -o $(TARGET).so

$(TARGET).o: $(TARGET).cpp
    g++ -I$(PYTHON) -I$(BOOST_INC) -c -fPIC $(TARGET).cpp

And this works. It builds a 'so' file for me which I can import from python.

Now the question: how to get this for cmake?

I wrote in main CMakeList.txt:

...
find_package(Boost COMPONENTS filesystem system date_time python REQUIRED)
message("Include dirs of boost: " ${Boost_INCLUDE_DIRS} )
message("Libs of boost: " ${Boost_LIBRARIES} )

include_directories(
    ${Boost_INCLUDE_DIRS}
        ...
)

target_link_libraries(Themisto
    ${Boost_LIBRARIES}
    ...
)
...

message calls show:

Include dirs of boost: /usr/include
Libs of boost: /usr/lib/libboost_filesystem-mt.a/usr/lib/libboost_system-mt.a/usr/lib/libboost_date_time-mt.a/usr/lib/libboost_python-mt.a

Ok, so I've added simple .cpp-file for my project with include of <boost/python.hpp>. I get an error at compiling:

/usr/include/boost/python/detail/wrap_python.hpp:50:23: fatal error: pyconfig.h: No such file or directory

So it doesn't take all need include directories.

And second question:

How to organize 2-step building of script-cpp files? In makefile I showed there are TARGET.o and TARGET.so, how to process that 2 commands in cmake?

As I understand, the best way is to create subproject and do something there.

Thanks.

You are missing your include directory and libs for python in your CMakeList.txt. Use the PythonFindLibs macro or the same find_package strategy you used for Boost

find_package(Boost COMPONENTS filesystem system date_time python REQUIRED)
message("Include dirs of boost: " ${Boost_INCLUDE_DIRS} )
message("Libs of boost: " ${Boost_LIBRARIES} )

find_package(PythonLibs REQUIRED)
message("Include dirs of Python: " ${PYTHON_INCLUDE_DIRS} )
message("Libs of Python: " ${PYTHON_LIBRARIES} )

include_directories(
    ${Boost_INCLUDE_DIRS}
    ${PYTHON_INCLUDE_DIRS}  # <-------
        ...
)

target_link_libraries(Themisto
    ${Boost_LIBRARIES}
    ${PYTHON_LIBRARIES} # <------
    ...
)
...
