Find package using cmake

[topazus]

The fmt-devel package is installed, but I tried to find fmt using cmake in xmake, but it does not find.

❯ xmake l find_package cmake::GTest
{
  links = {
    "gtest"
  },
  defines = {
    "GTEST_LINKED_AS_SHARED_LIBRARY"
  },
  libfiles = {
    "/usr/lib64/libgtest.so"
  },
  linkdirs = {
    "/usr/lib64"
  }
}

❯ xmake l find_package cmake::fmt
nil

❯ rpm -ql fmt-devel

Try pkgconfig::fmt or use offical package add_requires("fmt")

Yes, pkgconfig::fmt can be found, but why does cmake::fmt can not found?

Using cmake to find packages, its implementation has some hacks. It's not stable and needs to rely on various cmake parameter configurations. I don't recommend using the cmake package in the presence of the xmake-repo package.

if you want to use it, you can debug here.
