Я успешно создал собственный аддон узла с помощью napi и cmakejs. Но при добавлении простой библиотеки файл unix make, сгенерированный cmake-js, взрывается с
[50%] Связывание статической библиотеки CXX liblib_name.a

Пример свернутого проекта: https://github.com/Superlokkus/spielwiese/tree/napi
Корневые списки CMakeLists должны быть близкими или иметь намерение быть близкими к примерной версии cmakejs, просто с дополнительной функцией PARSE_CMAKEJS_PROPERTIES, которая также собирается с помощью команды CLI cmake, для хорошей разработки с IDE, такими как CLion. Однако проблема сохраняется при удалении функции PARSE_CMAKEJS_PROPERTIES.
Я добавил библиотеку с add_subdirectory, если вы удалите https://github.com/Superlokkus/spielwiese/blob/napi/CMakeLists.txt#L47 aka add_subdirectory(src/lib_name) и измените https://github.com/Superlokkus/spielwiese/blob/napi/CMakeLists.txt#L63 aka target_link_libraries(${PROJECT_NAME} PUBLIC ${CMAKE_JS_LIB} lib_name) на target_link_libraries(${PROJECT_NAME} PUBLIC ${CMAKE_JS_LIB}), а также удалите
https://github.com/Superlokkus/spielwiese/blob/napi/src/spielwiese.cpp#L3 aka #include <lib_name/lib_name.hpp>,
проект строится заново вкл. тест мокко. Однако добавьте библиотеку примеров, и вы снова получите ошибку.

PUBLIC

)
решает проблему, поэтому похоже, что cmakejs имеет некоторые проблемы с этой командой ?!
