Could not find mathglConfig.cmake

[linyuanchang]

I got the following errors when trying to use the package mathgl.

Selecting Windows SDK version 10.0.22000.0 to target Windows 10.0.19044.
CMake Error at D:/vcpkg/scripts/buildsystems/vcpkg.cmake:843 (_find_package):
  Could not find a package configuration file provided by "mathgl" with any
  of the following names:

    mathglConfig.cmake
    mathgl-config.cmake

  Add the installation prefix of "mathgl" to CMAKE_PREFIX_PATH or set
  "mathgl_DIR" to a directory containing one of the above files.  If "mathgl"
  provides a separate development package or SDK, be sure it has been
  installed.
Call Stack (most recent call first):
  CMakeLists.txt:16 (find_package)

But I really find the follow files:

MathGL2Config.cmake
MathGL2Targets.cmake

Is this a bug relate to the version?

MathGL2Config.cmake create a case-sensitive package name MathGL2, and MathGL should work, too.

(mathgl would work with mathgl2-config.cmake.)

[dg0yt]

But there is a port bug, too. The config fixup moves the package to share/mathgl, breaking the MathGL2 variant.
So only one name is left: MathGL.

Duplicates #22264.
