Non-standard install destination paths

[rwols]

Lines like this:

cmake-sbom/cmake/sbom.cmake

Line 732 in 6bc34fd

sbom_file(FILENAME ${CMAKE_INSTALL_LIBDIR}/$<TARGET_FILE_NAME:${SBOM_TARGET_TARGET}>

assume that the static library is installed into ${CMAKE_PREFIX_PATH}/${CMAKE_INSTALL_LIBDIR}/$<TARGET_FILE_NAME:${SBOM_TARGET_TARGET}>, but that may not necessarily be the case.

I tried looking into how to account for that, perhaps getting an INSTALL_DESTINATION property from the target, but it seems there is no such target property!

We could solve this by overriding the install() command and recording all install destinations. Not sure how that would look like exactly.

function(install)
  # ...
  # record ALL the install destinations of ALL files...
  # ...
  # invoke the original install() command
  _install(${ARGN})
endfunction()

This seems like a hard problem! I don't know how reliable it is to override built-in functions like this.

Overriding install() does not sound reliable. There is a install_manifest.txt, with all installed files, but that does not have the relation to the target anymore. For now, I would fallback to sbom_add(FILENAME ...) to add it manually when it is not default-installed. There is probably room for improvement.
