CMake Bugfix: Windows ggml find_package fix in llama-config.cmake.in file

[Emreerdog]

Review Complexity: Easy

Problem

In llama-config.cmake.in file, we are looking for the ggml cmake config file through find_package function in CMake which works normal in UNIX file architecture since cmake looks for config modules under lib/cmake directories.

However in Windows, since the library is installed under C:\Program Files\llama.cpp or C:\Program Files (x86)\llama.cpp folder, CMake looks for config modules based off of the names of the folders under the program files directory and it can't find the ggml library since it is not installed as an individual project on its own.

Fix

Adding a lookup hint location where the llama-config.cmake and ggml-config.cmake file reside together.

@Emreerdog Any chance you would provide the basic command you used to build/install? I am planning on adding some regression tests to the CI, and this would give me something to throw in the mix.

@bandoti I normally create the build directory under llama.cpp and do the compile and install:

mkdir build
cd build
cmake ..
cmake --build . --config Release -j

After the compilation is finished, I call this under the build directory:

cmake --install .

The local installation requires admin privileges though.

Okay great. Thanks for the contribution.
