It is possible to remove the template methods from my classes,

free functions instead and use them in a UFCS way.
Unfortunately I have not figured out UFCS properly, as my
approaches do
not work ( guess due to UFCS restrictions ).
That would not help, templates are instantiated and compiled
when they are used, not when they are declared.
Hence the idea of splitting the class. After the split, the class
has only non-template methods and is part of MyLib. Template UFCS
functions working with this class are in another module, and not
part of the lib. With this approach MyLib does not need to
recompile, only the UFCS functions module needs to recompile due
to different instantiations. UFCS works now for me btw.
I tried to not build MyLib at all, and use the sources
directly, but the
project setup is kind of confusing. Again, there is a setting
which I
seem to not understand fully. So one project, lets say
MyProject, has
only its own module files added to the VisualD project. I want
the
compiler to also use the MyLib source files, but do not want
to add them
to MyProject, reasoning bellow. There is one entry in the
project
properties, which should make this behavior possible, but it
doses not.
Why ?
Configuration Properties - Compiler - General - Additional
Imports
As far as I understand this setting, I am supposed to enter
module
search paths.
This is correct.

You should add a dependency in the "Project -> Project
Dependencies" dialog. This will ensure proper rebuilds and add
the library to the command line of dependent projects.
The idea is to NOT create a lib, but just use the source code
from MyLib in MyProject as additional includes. No project
dependencies. I was hoping that some .obj files are still
available from last builds, and do not need to recompile, as they
are up to date ( reason for question about not cleaning files ).
The modules form MyProject do import the MyLib modules properly,
I do not get compiler errors. However, the compiler should create
Object files from MyLib modules, and the linker should link them.
But he does not.
On the other hand, when I add MyLib modules to MyProject (
Rightclick MyProject - add - existing item... MyLib source files
) then linking works. I do not understand why the later step is
necessary.
