Thanks for reporting the issue with all relevant details.
I had a quick run on the example posted above ( using cmake 3.15.2 - the one which is installed with me locally ), and was able to build it successfully. Will try it out with the cmake version used in the test above (i.e 3.19)

Ok. I validated using cmake-3.20.1 too, and it works fine. Can you ensure that opentelemetry-cpp is installed correctly in the system path, probably check the content of below directories ( on *nix/wsl ):

$  ls /usr/local/include/opentelemetry/

The only difference I can spot is I'm missing the file - opentelemetry-cpp-target-noconfig.cmake

[ThomsonTan]

@jefjos what is the linking issue? From the original post, there is CMake warnings but the build files were still produced. Would the build succeed based on that?

[jefjos]

The subsequent build with ninja is failing with the following error

ninja
ninja: error: 'opentelemetry-cpp::version-NOTFOUND', needed by 'hello_cmake', missing and no known rule to make it

After manually copied the noconfig.cmake to lib directory able to link it.

@jefjos where is opentelemetry-cpp installed? I saw below option is passed to cmake, was it intended to install opentelemetry-cpp under the test project folder like hello-cmake/out? If opentelemetry-cpp is installed to system default location like /usr/local/include and /usr/local/lib, below option should not be passed as a customized path.

-DCMAKE_INSTALL_PREFIX:PATH="hello-cmake/out/install/WSL-GCC-Debug"

[jefjos]

I tried again after deleting all cached files and running cmake -G "Ninja"

Getting same warnings and build error

[jefjos]

Have added the following lines in CMakeLists.txt as a workaround for now

set_target_properties(opentelemetry-cpp::version PROPERTIES IMPORTED_LOCATION "${OPENTELEMETRY_CPP_LIBRARY_DIRS}/libopentelemetry_version.a")
set_target_properties(opentelemetry-cpp::common PROPERTIES IMPORTED_LOCATION "${OPENTELEMETRY_CPP_LIBRARY_DIRS}/libopentelemetry_common.a")
set_target_properties(opentelemetry-cpp::trace PROPERTIES IMPORTED_LOCATION "${OPENTELEMETRY_CPP_LIBRARY_DIRS}/libopentelemetry_trace.a")

set_target_properties(opentelemetry-cpp::resources PROPERTIES IMPORTED_LOCATION "${OPENTELEMETRY_CPP_LIBRARY_DIRS}/libopentelemetry_resources.a")

[ThomsonTan]

@jefjos based on your listing above, the problem is you are missing the configuration specific target CMake file in below directory, like opentelemetry-cpp-target-debug.cmake. Could you please clean all the installed files for opentelemetry-cpp and re-build and re-install it? I did the build and installation in WSL as well and got the config file there.

ls /usr/local/lib/cmake/opentelemetry-cpp/
opentelemetry-cpp-config-version.cmake opentelemetry-cpp-target.cmake
opentelemetry-cpp-config.cmake

[owent]

The only difference I can spot is I'm missing the file - opentelemetry-cpp-target-noconfig.cmake

The cmake config file are installed under <CMAKE_INSTALL_PREFIX>/lib/cmake/opentelemetry-cpp or <CMAKE_INSTALL_PREFIX>/lib64/cmake/opentelemetry-cpp .
The opentelemetry-cpp-target.cmake will include all opentelemetry-cpp-target-*.cmake and the suffix of opentelemetry-cpp-target-*.cmake depend on what you pass to --config if you use cmake --build ... to build.
For example:
When using cmake --build . --target install --config RedWithDebInfo to build opentelemetry-cpp, opentelemetry-cpp-target-relwithdebinfo.cmake will be installed.When nothing passed into --config, opentelemetry-cpp-target-noconfig.cmake will be installed.

@jefjos @nkrishnappa please update whether you are able to build it successfully with the latest release.
