How to create a postinstall or preinstall with cmake (macOS
For example,
I use the
CPACK_PREFLIGHT_SCRIPT or CPACK_POSTFLIGHT_SCRIPT
But it doesnt work .

cmakelist
set(CPACK_PREFLIGHT_SCRIPT “${PROJECT_BINARY_DIR}/preinstall.sh”)
set(CPACK_POSTFLIGHT_SCRIPT “${PROJECT_SOURCE_DIR}/scripts/postinstall.sh”)

preinstall.sh
#!/bin/sh
mkdir -p /User/user/Desktop/123
echo “Here is do the post install”
exit 0
