vcpkg add new library but it cannot be found - c++

Question

I tries to add a new library at vcpkg, so I have wrote a CONTROL file and portfile.cmake file. When I run the installation, it's successful:
./vcpkg.exe install gf:x64-windows
Computing installation plan...
The following packages will be built and installed:
gf[core]:x64-windows
Starting package 1/1: gf:x64-windows
Building package gf[core]:x64-windows...
-- SOURCE_PATH: C:/path/to/vcpkg/buildtrees/gf/src/v0.15.0

Installing package gf[core]:x64-windows...
Installing package gf[core]:x64-windows... done
Elapsed time for package gf:x64-windows: 52.05 s
Total elapsed time: 52.1 s
The package gf:x64-windows provides CMake targets:
find_package(gf CONFIG REQUIRED)
target_link_libraries(main PRIVATE gf::gf0)
find_package(gfcore CONFIG REQUIRED)
target_link_libraries(main PRIVATE gf::gfcore0)
find_package(gfnet CONFIG REQUIRED)
target_link_libraries(main PRIVATE gf::gfnet0)
But when I want use this library into another project, I have this error:
cmake -A x64 -DCMAKE_TOOLCHAIN_FILE=C:/path/to/vcpkg/scripts/buildsystems/vcpkg.cmake ..

CMake to find a package configuration file provided by "gf", but CMake did

Could not find a package configuration file provided by "gf" with any of
the following names:
gfConfig.cmake

Add the installation prefix of "gf" to CMAKE_PREFIX_PATH or set "gf_DIR" to
a directory containing one of the above files. If "gf" provides a separate
development package or SDK, be sure it has been installed.

Where is my error?
The library can be found here: https://github.com/GamedevFramework/gf
The project here: https://github.com/Hatunruna/ggj2020
This is the CONTROL file for gf:
Source: gf
Version: 0.15
Description: Gamedev Framework (gf) is a framework to build 2D games in C++14.
And the portfile.cmake:
find_program(GIT git)

set(GIT_TAG "loading_thread")
set(SOURCE_PATH ${CURRENT_BUILDTREES_DIR}/src/${GIT_TAG})

Answer 1

Finally, I found the problem. vcpkg needs to have a separated folder for each targets.
So I have change the portfile.cmake:
find_program(GIT git)
# Same as previous...
vcpkg_fixup_cmake_targets(CONFIG_PATH lib/cmake TARGET_PATH "share/gf_tmp")
vcpkg_copy_pdbs()
file(RENAME "${CURRENT_PACKAGES_DIR}/share/gf_tmp/gfcore" "${CURRENT_PACKAGES_DIR}/share/gfcore")
file(RENAME "${CURRENT_PACKAGES_DIR}/share/gf_tmp/gf" "${CURRENT_PACKAGES_DIR}/share/gf")
file(RENAME "${CURRENT_PACKAGES_DIR}/share/gf_tmp/gfnet" "${CURRENT_PACKAGES_DIR}/share/gfnet")
file(REMOVE_RECURSE
"${CURRENT_PACKAGES_DIR}/debug/share"
"${CURRENT_PACKAGES_DIR}/debug/include"
"${CURRENT_PACKAGES_DIR}/share/doc"
"${CURRENT_PACKAGES_DIR}/share/gf_tmp"
)
file(INSTALL ${SOURCE_PATH}/LICENSE.txt DESTINATION ${CURRENT_PACKAGES_DIR}/share/gf RENAME copyright)
