BSD Make stumples over file names which contain spaces

[sikmir]

BSD Make (in contrast to GNU Make) requires that targets with whitespaces must be enclosed in quotes.
Easiest way to fix is rename.

Steps to reproduce

$ make Mapper-manual
Built target Mapper-manual-pages
make[3]: don't know how to make doc/manual/Mapper\. Stop

Root cause:

$ grep "doc/manual/Mapper\\" doc/manual/CMakeFiles/Mapper-manual.dir/build.make
doc/manual/CMakeFiles/Mapper-manual: doc/manual/Mapper\ 0.6.6\ Manual.qhc
doc/manual/Mapper\ 0.6.6\ Manual.qhc: doc/manual/Manual.qhcp
doc/manual/Mapper\ 0.6.6\ Manual.qhc: doc/manual/html/index.qhp
doc/manual/Mapper\ 0.6.6\ Manual.qhc: doc/manual/html/index.qhp
doc/manual/Mapper\ 0.6.6\ Manual.qch: doc/manual/Mapper\ 0.6.6\ Manual.qhc
Mapper-manual: doc/manual/Mapper\ 0.6.6\ Manual.qhc
Mapper-manual: doc/manual/Mapper\ 0.6.6\ Manual.qch

$ make Mapper_symbol_sets
make[1]: don't know how to make symbol\. Stop

Root cause:

$ grep "symbol\\" CMakeFiles/Makefile2
symbol\ sets/all: symbol\ sets/CMakeFiles/Mapper_symbol_sets.dir/all
...

Actual behaviour

Build fails.

Expected behaviour

Build successed.

Configuration

Mapper Version: latest
Operating System: any BSD

I will look into this when I finished the restructuring (simplifying) the build system (#674).

Isn't this an issue of using a matching combination of CMake generator and native build system?
Do we need to support BSD make? Alternatives (GNU make, Ninja) should be available where needed. The current configuration works out of the box for a wide variety of systems.

I don't know if it's possible to force CMake to generate bsd-compatible makefile (actually just enquote the paths with whitespaces). Anyway, this is very minor issue and created just to be aware of it. Surely it's not a problem at all to use 'gmake' instead of 'make' on BSD systems.
