Hotfix for OpeniamgeIO compilation

To avoid the following error when compiling OpenImageIO:

/home/oargentieri/Documents/PullGithub/OpenColorIO-2.3.0/install/lib64/libOpenColorIO.so.2.3: undefined reference to `pystring::replace(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int)'
/home/oargentieri/Documents/PullGithub/OpenColorIO-2.3.0/install/lib64/libOpenColorIO.so.2.3: undefined reference to `pystring::os::path::isabs(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
/home/oargentieri/Documents/PullGithub/OpenColorIO-2.3.0/install/lib64/libOpenColorIO.so.2.3: undefined reference to `pystring::os::path::basename(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
collect2: error: ld returned 1 exit status
gmake[2]: *** [bin/strutil_test] Error 1
gmake[1]: *** [src/libutil/CMakeFiles/strutil_test.dir/all] Error 2
gmake: *** [all] Error 2

At the end of pystring compilation, in the prefix install directory, you need to also have an include directory with the pystring source code. So you can just copy the source code cpp files into <PYSTRING_SOURCE_DIR>/install/include/

cp <PYSTRING_SOURCE_DIR>/src/*.h <PYSTRING_SOURCE_DIR>/install/include/
cp <PYSTRING_SOURCE_DIR>/src/*.cpp <PYSTRING_SOURCE_DIR>/install/include/

This is not a good solution, but it works. A real solution would be to compile pystring as a static library and link it to OpenImageIO.
