[CMake] CPack - NSIS - Add multiple directory paths inside PATH environment variable

[Romain LEGUAY]

Hello everyone,

I make a library and when I install it, I want to put inside the PATH 
environment variable the include directory path and the library path.

I write this:

set(CPACK_NSIS_MODIFY_PATH ON)
set(CPACK_NSIS_EXTRA_INSTALL_COMMANDS "\${EnvVarUpdate} \"$0\" \"PATH\" 
\"A\" \"HKCU\" \"${MY_INCLUDE_DIR};${MY_LIB_DIR}\"")

where MY_INCLUDE_DIR and MY_LIB_DIR are just some relative path.

Unfortunately, my PATH variable doesn't change.

Where can I found some example to modify the PATH whit NSIS and CPack?

Thank you.

Romain
