For FLTK. If I set FLTK\_DIR to a build directory in the CMakeLists.txt file and then run find\_package( FLTK REQUIRED NO\_MODULE ), I get an error message:

CMake Error at mrViewer/src/CMakeLists.txt:53 (FIND\_PACKAGE):  
Could not find a package configuration file provided by “FLTK” with any of  
the following names:

```
FLTKConfig.cmake
fltk-config.cmake

```

Add the installation prefix of “FLTK” to CMAKE\_PREFIX\_PATH or set  
“FLTK\_DIR” to a directory containing one of the above files. If “FLTK”  
provides a separate development package or SDK, be sure it has been  
installed.

If I set FLTK\_DIR in the command-line all works fine. I already checked the cache and it is not that.

`FLTK_DIR`'s build directory may not contain a config file, so that wouldn’t necessarily work. The named files need to exist for `_DIR` variables to work with `find_package(NO_MODULE)`.

FLTK\_DIR contains a FLTKConfig.cmake file. However cmake does not find it.

As I said, if I set FLTK\_DIR from the command-line with -DFLTK\_DIR=path/to/fltk/build it all works well.

Could you use `cmake --debug-find` to get the information related to searching for FLTK?

I got the information and my build directory is not listed. Most directories seem part of $PATH.

```

The build directory should be ~/code/lib/fltk-x11/build-linux.

Once I run it with -DFLTK\_DIR, the directory is found as the first and only path.

That makes sense. If a `_DIR` variable is not useful, its value is cleared (historical behavior; it’s annoying), so there is probably some second-configure issues popping up here.

Second-configure issues. Like what? What should I look for?

I mean issues that arise because of cache differences that make a project do different things with `cmake .` versus `cmake . && cmake .` (which CI usually skips, so it is only developers that see it).

You say that it is now found with `FLTK_DIR`, so is this resolved?

No. It finds FLTK\_DIR only if I pass it command-line (and run it afterwards, too). However, what I really wanted was to set the FLTK\_DIR path in the CMakeLists.txt file and that does not work. I really never wanted to pass the path command-line. I wanted to hard-code it in the CMakeLists.txt file.

</div>

Did you already tried to make FLTK\_DIR a cache variable, i.e. `set(FLTK_DIR "path/to/fltk/build" CACHE FILEPATH "Package config directory of FLTK")`? One difference between a CMake command line argument and a plain `set` command (without CACHE keyword) is that the former creates a CACHE entry while the latter does not. And the cached variable is shadowing the normal variable.

Yes. I tried setting FLTK\_DIR as a CACHE variable to no effect.
