I have setup my pybind11 for building python modules written in c++. I have python3.6, and python3.7 installed on my ubuntu system, I installed both python3.6-dev and python3.7-dev. then I setup my cmakelists.txt file for my project as following: set(PYTHONVERSION "3.7") # None of the lines below works add_definitions(-DPYBIND11_PYTHON_VERSION="${PYTHONVERSION}") set(PYBIND11_PYTHON_VERSION ${PYTHONVERSION} CACHE STRING "") set(PYBIND11_PYTHON_VERSION ${PYTHONVERSION}) find_package(Python ${PYTHONVERSION} COMPONENTS Development Interpreter) set(TARGET proj) pybind11_add_module(${TARGET} MODULE proj.cpp) target_include_directories(${TARGET} PUBLIC ${CMAKE_CURRENT_SOURCE_DIR}) if (Python_FOUND) target_include_directories(${TARGET} PUBLIC ${Python_INCLUDE_DIRS}) endif() However, when I build the project it still generates modules for python3.6 instead of python3.7. Below is my output from cmake, I found cmake finds python3.6 first, where I didn't even call findpython. [cmake] Not searching for unused variables given on the command line.
