How to connect tmxlite to cmake SFML project with VCPKG or any other means (Decided)

Decided(Alexander Neumann):

In any directory convenient for you, create a file 'Findtmxlite.cmake'
Write the paths, they may differ with us.


#Findtmxlite.cmake
set(VCPKG_PATH "${USER_PROFILE}/vcpkg")
set(VCPKG_INCLUDE_DIR "${VCPKG_PATH}/installed/${VCPKG_TARGET_TRIPLET}/include")
set(VCPKG_LIBRARY_DIR "${VCPKG_PATH}/installed/${VCPKG_TARGET_TRIPLET}/lib")

# Set up tmxlite search

# Find path to tmxlite header files
find_path(tmxlite_INCLUDE_DIR NAMES tmxlite/Map.hpp PATHS VCPKG_INCLUDE_DIR)

# Find the tmxlite library
find_library(tmxlite_LIBRARY NAMES tmxlite PATHS VCPKG_LIBRARY_DIR)

# Create an imported target for tmxlite
add_library(tmxlite INTERFACE)

# Specify the path to the tmxlite header files
target_include_directories(tmxlite INTERFACE ${tmxlite_INCLUDE_DIR})

# Link the tmxlite library to the target
target_link_libraries(tmxlite INTERFACE ${tmxlite_LIBRARY})

Add the following line to the project

    set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "path/to/Findtmxlite.cmake/dir")

After these steps you can use tmxlite in your project

find_package(tmxlite REQUIRED)
add_executable (tester "main.cpp")
target_link_libraries(tester PRIVATE tmxlite)

tmxlite developers please help Severity Code Description Project File String Suppression status CMake Error at C:/Users/Agenteec/vcpkg/scripts/buildsystems/vcpkg.cmake:843 (_find_package): By not providing "Findtmxlite.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "tmxlite", but CMake did not find one.

Could not find a package configuration file provided by "tmxlite" with any of the following names:

tmxliteConfig.cmake tmxlite-config.cmake

Add the installation prefix of "tmxlite" to CMAKE_PREFIX_PATH or set "tmxlite_DIR" to a directory containing one of the above files. If "tmxlite" provides a separate development package or SDK, be sure it has been installed. C:/Users/Agenteec/vcpkg/scripts/buildsystems/vcpkg.cmake 843 Maybe I misspelled the package name.

Solution

You need to write your own Find<Module>.cmake for tmxlite since it neither install pkg-config files nor cmake files.

In the Find<Module>.cmake you need to do the following:

search for the header directory via find_file/find_path
search for the (release/debug) library via find_library
(if applicable) find_package other dependencies
define an imported target and use the above to set it up.
link the defined imported target to your target

(and no you don't need any vcpkg specific hacks here.)
