Add install/build options to requirements.txt

[marcovc]

Is there a way to add install options to the requirements.txt file, such as:

package1 -DOption1=1
package2 -DOption2=2

?

Thanks

Yes, this is already supported, see here.

Thanks. It seems it is not getting the defines in this requirements.txt file :

MiniZinc/libminizinc/archive/develop -DCMAKE_CXX_FLAGS="-fPIC" -DCMAKE_C_FLAGS="-fPIC"

(but it works if I call it like cget install MiniZinc/libminizinc/archive/develop -DCMAKE_CXX_FLAGS="-fPIC" -DCMAKE_C_FLAGS="-fPIC")

Any clues why?

You cant set those flags because they are usually set by the toolchain. Although there should be a way to add additional flags for some projects.

However, for your example, you can add -DCMAKE_POSITION_INDEPENDENT_CODE=On to add the -fPIC flag.

I see. But then why does it work if set those flags when I call cget? I.e., this: cget install -Detc works in this case.

Variables like CMAKE_CXX_FLAGS are set by cget's internal cmake toolchain file, so it will override the flags set by -Detc.
