Based on this question CMake cpprestsdk I tried to create a specific target from cpprestsdk source code. First, I cloned the github project into /home/user/git/cpprestsdk

Then, I created the CmakeLists.txt file

project(ProjectName) find_package(cpprestsdk CONFIG REQUIRED) target_link_libraries(ProjectName PRIVATE cpprestsdk::cpprestsdk_boost_internal)

and the cmake command:

cmake -DCMAKE_PREFIX_PATH=/home/user/git/cpprestsdk/Release/src .

and got the following error:

CMake Error at cpprestsdk/Release/src/cpprestsdk-config.cmake:25 (include): include could not find load file: /home/ebalbar/git/cpprestsdk/Release/src/cpprestsdk-targets.cmake Call Stack (most recent call first): CMakeLists.txt:2 (find_package) CMake Error at CMakeLists.txt:3 (target_link_libraries): Cannot specify link libraries for target "ProjectName" which is not built by this project.

The target file can be found under /home/user/git/cpprestsdk/Release/src/CMakeFiles/Export/lib/cmake/cpprestsdk/cpprestsdk-targets.cmake

So the question is how to build cpprestsdk::cpprestsdk_boost_internal target?

Thanks in advance!

    "First, I cloned the github project into /home/user/git/cpprestsdk" - Then you should built the project and install it. And CMAKE_PREFIX_PATH should contain the installation prefix which you have passed when installing the project. Only after that find_package(cpprestsdk) will work. Commented Nov 14, 2024 at 15:14

as @Tsyvarev pointed out first the library should be built and installed.

cmake . cmake --build . cmake --install . --prefix <install_folder>

Then, the application CMakeList.txt should look like this:

cmake_minimum_required(VERSION 3.16) # In your project's CMakeLists.txt project(ProjectName) set(CMAKE_PREFIX_PATH "<install_folder>") find_package(cpprestsdk REQUIRED) add_library(my_target SHARED main.cpp) # Link to `cpprestsdk::cpprestsdk_openssl_internal` in your target target_link_libraries(my_target cpprestsdk::cpprestsdk_openssl_internal)

then I could build the application with the following cmake commands:

cmake . cmake --build .
