Lazarus sets the working directory to the project directory when

Fine :-)

The 'in' modifier works here.

It didn't work for me with relative pathes, like
  uses myUnit in '..\myUnit.pas';
(Windows, obviously ;-)

Hint: Both compiler and lazarus automatically changes the path delimiter and searches exact/lower/upper case for the file name (not path).


While Lazarus could find that unit, FPC could not :-(

There might be a problem with "uses" in the project file, where "in" is allowed, and with uses of the same file in other units?

The 'in' modifier is troublesome and is always the inferior solution compared to search paths. Lazarus searches relative to the unit, the compiler relative to its working directory. The reason is that the IDE has not a single working directory, but each project, each package and each tool have their own working directories, so units can have 0..n different working directories.
Delphi uses the 'in' modifier mostly to mark units as part of the project.
