Maybe the problem is double defining CMAKE_INSTALL_PREFIX which is
already set in $(CROSS_CMAKE_USR), see:
% ptxdist print CROSS_CMAKE_USR
-DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE:STRING=RelWithDebInfo
-DCMAKE_TOOLCHAIN_FILE='[removed]'
It's some time ago, but I guess we had the same problem.
$(CROSS_CMAKE_USR) is set in rules/pre/Rules.make from line 241:
241 CROSS_CMAKE_USR := \
242 -DCMAKE_INSTALL_PREFIX=/usr \
243 -DCMAKE_BUILD_TYPE:STRING=RelWithDebInfo \
244 -DCMAKE_TOOLCHAIN_FILE='${PTXDIST_CMAKE_TOOLCHAIN_TARGET}'
So what we do for our CMake based projects, if we want to change
CMAKE_INSTALL_PREFIX or CMAKE_BUILD_TYPE (changing the toolchain file
path makes no sense IMHO) we go like this:
54 FOO_CONF_TOOL := cmake
55 # this is $(CROSS_CMAKE_USR) but with adapted install prefix
56 FOO_CONF_OPT := \
57 -DCMAKE_INSTALL_PREFIX=$(PTXCONF_FOO_PREFIX) \
58 -DCMAKE_BUILD_TYPE:STRING=$(PTXCONF_FOO_BUILD_TYPE) \
59 -DCMAKE_TOOLCHAIN_FILE='${PTXDIST_CMAKE_TOOLCHAIN_TARGET}'
And then FOO_CONF_OPT += -DANYTHING=foo
PTXCONF_FOO_PREFIX and PTXCONF_FOO_BUILD_TYPE are more or less defined
in rules/foo.in and the comment is to remind we are overwriting ptxdist
defaults here. So what we actually do is not using CROSS_CMAKE_USR but
redefining the three variables it would set.
