I’m trying to build [tesseract](https://github.com/tesseract-robotics/tesseract) repo on Windows 10 22H2.
I was told to use `colcon` to build the repo. I’m new to `colcon` and `cmake`. I cloned the repo to `C:\Temp\colcon_ws\src` and ran `colcon build` from `x64 Native Tools Command Prompt for VS 2022` terminal. But, I get the cmake error below.
Even if I use Cmake-Gui I still get that error message.
What could be wrong?
```auto
C:\Temp\colcon_ws>call install\local_setup.bat
C:\Temp\colcon_ws>colcon build
Starting >>> ros_industrial_cmake_boilerplate
Finished <<< ros_industrial_cmake_boilerplate [0.81s]
Starting >>> tesseract_common
--- stderr: tesseract_common
CMake Error at CMakeLists.txt:4 (find_package):
Could not find a configuration file for package
"ros_industrial_cmake_boilerplate" that is compatible with requested
version "".
The following configuration files were considered but not accepted:
C:/Temp/colcon_ws/install/ros_industrial_cmake_boilerplate/lib/cmake/ros_industrial_cmake_boilerplate/ros_industrial_cmake_boilerplate-config.cmake, version: 0.4.6 (64bit)

```
FYI, I was, however, able to build that repo on Linux. So, the problem has to be with how I use the cmake on Windows.

I think you’re probably in a 32bit build and it finds a 64bit build and (rightly) rejects it. Can you confirm that you’re trying to build your code in 64bit.

But, I start `x64 Native Tools Command Prompt for VS 2022 terminal` which is `x64`. What am I missing?

I see that, but can you check to see what CMake ends up finding? It _should_ be the 64-bit version, but maybe something else in the env is confusing it.
Another thing to try is passing `--debug-find` to CMake. Maybe that will help?

I added `--debug-find` flag to CMake-GUI (instead of `x64 Native Tools Command Prompt for VS 2022` terminal) and it still gives me the same message. No new verbos text. To add `--debug-find` flag in CMake-GUI `CMAKE_MESSAGE_LOG_LEVEL` and `CMAKE_DEBUG_FIND_PACKAGE` entries as shown in the image.
How do I check to see what CMake ends up finding?

Maybe, use “project()” before “find\_package()” will fix this? Idk the reason, but I solved this problem, at least for now.

Oh, that’s probably on the `CMAKE_SIZEOF_VOID_P` check that (I think) gets generated in the compatibility checks for packages.
