@BillyONeal I'm not sure how to handle the path issue:

From microsoft/vcpkg#44188 (comment):

Also, Paths are also invalid:

"fileName": ".//home/igor/development/vcpkg/vcpkg_original/ports/bzip2/bzip2.pc.in",

The code expects relative paths:

but we feed in absolute paths by including the port directory:

However, I think we should be using absolute paths because we might lose the information of where a file comes from in case of overlay ports.

On the other hand, absolute paths are invalid after downloading from a binary cache on different machines.

Right, this is why the paths have to be relative.

However, I think we should be using absolute paths because we might lose the information of where a file comes from in case of overlay ports.

That's why the SHAs of the files are also in the SPDX. It isn't there's a hard link between any particular absolute path and anything else, any more than there is between that relative path and anything else.

Can you add a test? Would merge this with one.

Hi @BillyONeal,

I added a unit test to check the correct replacement of ${VERSION} in all CMake functions and to ensure that all instances of those functions are found.

As you proposed, I didn't fix the absolute path issue mentioned in microsoft/vcpkg#44188. Therefore, plese don't close that issue yet - I will fix the absolute path issue in a different PR.
