Building with CMake

[sbendt]

Hi,

Probably not an issue, more of a question.
I am trying to setup a C++ application that will be using ZeroMQ with the azmq, but I am a bit stuck on setting up the CMake configuration for my application.

I would like to have everything in the CMake configuration, and not rely on anything being installed before the build.

From my CMakeLists.txt:

message(STATUS "ZeroMQ...")
include(FetchContent)
FetchContent_Declare(
ZeroMQ
GIT_REPOSITORY https://github.com/zeromq/zeromq4-x
GIT_TAG 267699b1ce7791bb360a794b9230b21676129612 # v4.0.10
)

set(AZMQ_NO_TESTS, ON)
set(AZMQ_BUILD_TESTS, OFF)
message(STATUS "azmq...")
FetchContent_Declare(
azmq
GIT_REPOSITORY https://github.com/zeromq/azmq
GIT_TAG 7da2fd0 # v1.0.3
)

FetchContent_MakeAvailable(ZeroMQ azmq)

CMake fails with:
[cmake] CMake Error at C:/msys64/mingw64/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
[cmake] Could NOT find ZeroMQ (missing: ZeroMQ_INCLUDE_DIRS ZeroMQ_LIBRARIES)
[cmake] (Required is at least version "4.0")
[cmake] Call Stack (most recent call first):
[cmake] C:/msys64/mingw64/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:600 (_FPHSA_FAILURE_MESSAGE)
[cmake] build/_deps/azmq-src/config/FindZeroMQ.cmake:77 (find_package_handle_standard_args)
[cmake] build/_deps/azmq-src/CMakeLists.txt:43 (find_package)

Can/should I assign those DIRS manually, or is this something ZeroMQ CMakeLists.txt should assign?
