I do not understand. I never add something to .cproject by hand. I
have a hand-edited Makefile, so the compiler/linker flags are not used.
  My setting is the following: in the makefile I have

LIBS = \
-I$(JDK_HOME)/include \
-I$(JDK_HOME)/include/linux

But on Ubuntu, $JDK_HOME is not defined, so she has to change the
default build command to

make LIBS=-I/path/to/her/jdk/include LIBS+=-I/path/to/her/jdk/include/linux

Note that

make "LIBS=-I/path/to/her/jdk/include -I/path/to/her/jdk/include/linux"

is not possible yet (https://bugs.eclipse.org/bugs/show_bug.cgi?id=222390).

But exactly this, the default make command, is stored in .cproject.

Furthermore, I have different makefiles for different platforms, so the
build directory changes between machines as well. I guess it should be
possible to make a cross-platform makefile, but I don’t know how.

Formatter settings can be exported from the preference page. They are
workspace general (for Java, you can have Project specific formatter
settings), so you would have to store them elsewhere. It is also
possible to export all Eclipse settings (File → Export → General).
