Hi everyone,

I need help solving this cmake boost python3 find problem when trying to compile cv_bridge. The colcon error message:

> colcon build --symlink-install --merge-install
...    
--- stderr: cv_bridge
    CMake Error at C:/Program Files/CMake/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
      Could NOT find Boost (missing: python3) (found version "1.76.0")
    Call Stack (most recent call first):
      C:/Program Files/CMake/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:594 (_FPHSA_FAILURE_MESSAGE)
      C:/Program Files/CMake/share/cmake-3.22/Modules/FindBoost.cmake:2360 (find_package_handle_standard_args)
      CMakeLists.txt:32 (find_package)

What I have tried:

• Installing different versions of boost: 1.58, 1.67, 1.76
• Adding to BoostINCLUDEDIRS the path to the boost libraries in the CMakeLists.txt of cv_bridge:

---

 if(NOT ANDROID)
      list(APPEND Boost_INCLUDE_DIRS "C:/Program Files/boost/boost_1_76_0")
      list(APPEND Boost_INCLUDE_DIRS "C:/Program Files/boost/boost_1_76_0/stage/lib")
      find_package(PythonLibs)

---

• Renaming the "libboostpython38-vc142-mt-gd-x64-176.lib" to "libboostpython38.lib" and "libboostpython3.lib"
• Compiling Boost from source with bootstrap.bat and b2 or installing with the zip file.
• Looked for answers here and elsewhere, which led me to try the above points

I have run out of ideas, please any help will be greatly appreciated!
