Hi,
and thanks for your quick reply!
Starting from a minimal, stripped down version of my build
configuration (thx for the tip!) I found that what I described
initially actually works. The reason it was not working was, that I
had turned the CPACK_SET_DESTDIR flag on in another place. After
removing the relevant SET() directive the installation prefixes worked
as desired.
For the record, this is my minimal, stripped down working version:
8<======== CMakeLists.txt =============
cmake_minimum_required(VERSION 3.2)
project(stripped-down C)
add_executable(main main.c)
install(TARGETS main
RUNTIME DESTINATION bin
)
set(CPACK_GENERATOR "DEB;TGZ")
set(CPACK_PROJECT_CONFIG_FILE ${CMAKE_SOURCE_DIR}/package.txt)
set(CPACK_PACKAGE_CONTACT "Some One <some.one at somewhere.com>")
include(CPack)
8<=================================
8<======== ${CMAKE_SOURCE_DIR}/package.txt) =============
IF (CPACK_GENERATOR MATCHES "DEB")
set(CPACK_PACKAGING_INSTALL_PREFIX "/opt")
ELSEIF(CPACK_GENERATOR MATCHES "TGZ")
set(CPACK_PACKAGING_INSTALL_PREFIX "")
ENDIF()
8<==================================================
Best regards,
Rainer
