Remove version requirement from fmt find_package 

By introducing 'no module' support this inadvertently triggered the find_package to use the "full version" version selection.

From https://cmake.org/cmake/help/latest/command/find_package.html#version-selection:

> When the [version] argument is given, Config mode will only find a version of the package that claims compatibility with the requested version (see format specification).

FMT does not set this configuration https://github.com/fmtlib/fmt/blob/7.1.3/support/cmake/fmt-config.cmake.in... but regardless it would not be "any compatibility" based on version semantics.

Which causes this error. v1.8.2 builds perfectly fine.

```
CMake Error at CMakeLists.txt:181 (find_package):
  Could not find a configuration file for package "fmt" that is compatible
  with requested version "5.3.0".

  The following configuration files were considered but not accepted:

    /home/proj/build/e98598522b7c484d9220bffc7ec84474515facbc/fmt-config.cmake, version: 7.1.3
```
