Could NOT find liblcf (missing: LIBLCF_LIBRARY) (found version "0.7.0")

[papoteur-mga]

Trying to build easyrpg for Mageia and update it, I found an error which was already reported, but solved with the way of static library, what we avoid in distribution.

What surprise me is that something is found, because version number is reported. The shared library is at 0.7.0 version.

The problem was already present before I try to update to 0.7.0: http://pkgsubmit.mageia.org/autobuild/cauldron/x86_64/core/2022-11-15/easyrpg-player-0.6.2.3-2.mga9.src.rpm/build.x86_64.0.20221115174342.log

Can you surround the liblcf finding in cmake with this: and post the output of cmake?

set(CMAKE_FIND_DEBUG_MODE TRUE)

set(CMAKE_FIND_DEBUG_MODE FALSE)

Thanks for your quick reply.
I'm not sure of the place. What I obtain:

Can you verify where liblcf.so is located?

[papoteur-mga]

I found a fix (at least for me).
The issue is that PATHS in liblcf-config.make is set to /usr//usr/lib64 in our build of liblcf.
This comes from here:

liblcf/builds/liblcf-config.cmake.in

Line 61 in 0ed38af

PATHS ${_IMPORT_PREFIX}/@CMAKE_INSTALL_LIBDIR@

and

liblcf/builds/liblcf-config.cmake.in

Line 67 in 0ed38af

PATHS ${_IMPORT_PREFIX}/@CMAKE_INSTALL_LIBDIR@

It seems that CMAKE_INSTALL_LIBDIR already includes the PREFIX, thus ${_IMPORT_PREFIX}/ isn't needed.

moved to liblcf as obviously a problem with the cmake-config file
