- introduce WM_COMPILE_CONTROL variable to convey control information
into the build rules.
The convention (as per spack):
- '+' to select a feature
- '~' to deselect a feature
Eg, to select the gold linker, and disable openmp
(spaces are not required):
WM_COMPILE_CONTROL="+gold ~openmp"
CONFIG: accept FOAM_EXTRA_LDFLAGS for AMD, gold, Mingw linkers
CONFIG: generalize PROJECT_LIBS (-ldl used almost universally)
OLD timings:
~~~~~~~~~~~~~~~~~~
evaluate: -6.82572e+31 in 10.38 s
hard-coded 0: -6.82572e+31 in 0.2 s
hard-coded 1: -6.82572e+31 in 10.37 s
hard-coded 2: -6.82572e+31 in 0.24 s
New timings:
~~~~~~~~~~~~~~~~~~
evaluate: -6.82572e+31 in 0.11 s
