#
# Usage
# wmakeWindowsDlOpenLibs <build/applications/.../options>
#
# Description
# Extract library dependencies from the EXE_LIBS entry for Windows
# applications and emit as FOAM_DLOPEN_LIBS for use with setRootCase.H
# Forcibly dlOpen'ing these libraries ensures that they are truly loaded
# for the windows application binary.
#
# An alternative means is to define external entry points into particular
# libraries and linking with '-u symbol', which would possibly have a lower
# overhead but is more code-intrusive and somewhat ad hoc.

# Eg, build/.../basic/laplacianFoam/options -> laplacianFoam

# After the cpp stage, the EXE_LIBS (if they exist) will be on a single line
# Extract EXE_LIBS = -labc ..., ignoring -L and .o entries
#
# The libNames output comprises comma-separated quoted strings
# "lib1","lib2","libN"
# these are suitable for C-code or a std::initializer_list<fileName> etc.
# The $() sub-shell is unquoted to ensure we get whitespace splitting
# and read individual words, not lines.
