find_package fails to find ifm3d

[robinbansal08]

I built the ifm3d library version 1.6.0 from source with the option BUILD_SHARED_LIBS=OFF, and it was built successfully. However, in my C++ project, when I tried to include the ifm3d library, it failed to find it.

OS: Ubuntu 20.04

find_package(ifm3d 1.6.0 REQUIRED)

1.236 CMake Error at CMakeLists.txt:28 (find_package):
1.236   By not providing "Findifm3d.cmake" in CMAKE_MODULE_PATH this project has
1.236   asked CMake to find a package configuration file provided by "ifm3d", but
1.236   CMake did not find one.
1.236 
1.236   Could not find a package configuration file provided by "ifm3d" (requested
1.236   version 1.6.0) with any of the following names:
1.236 
1.236     ifm3dConfig.cmake
1.236     ifm3d-config.cmake
1.236 
1.236   Add the installation prefix of "ifm3d" to CMAKE_PREFIX_PATH or set
1.236   "ifm3d_DIR" to a directory containing one of the above files.  If "ifm3d"
1.236   provides a separate development package or SDK, be sure it has been
1.236   installed.

This issue does not occur if ifm3d library is built with the option BUILD_SHARED_LIBS=ON.

Hi @robinbansal08, I can confirm that I can reproduce this.

And actually, when building the library with BUILD_SHARED_LIBS=ON, I have a similar issue, when building our examples:

0.281 CMake Error at ods/CMakeLists.txt:44 (add_executable):
0.281   Target "ods_get_data" links to target "ifm3d::framegrabber" but the target
0.281   was not found.  Perhaps a find_package() call is missing for an IMPORTED
0.281   target, or an ALIAS target is missing?

We will work on fixing this.

In the meantime, please use the official release of ifm3d, the latest right now is 1.5.3. The 1.6.0 is a pre-released and (as you noticed) not fully tested.

Thank you for checking the issue. I have already tried version 1.5.3 and faced some issues (https://github.com/ifm/ifm3d/issues/455) because of which I tried newer version 1.6.0.
