looking on the code, I have found the dependencies in the custom commands.

-----------------------------------------------------------
ADD_CUSTOM_COMMAND(OUTPUT ${DYNCALL_SOURCE_DIR}/ConfigVars
COMMAND tar xzf ${CMAKE_CURRENT_SOURCE_DIR}/dyncall-0.3.tar.gz
COMMAND cd ${DYNCALL_SOURCE_DIR}
&& ./configure --prefix=${DYNCALL_INSTALL_DIR}
DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/dyncall-0.3.tar.gz)

ADD_CUSTOM_COMMAND(OUTPUT ${DYNCALL_LIBRARIES}
COMMAND make "CFLAGS=-O3 -fPIC"
COMMAND make install
DEPENDS ${DYNCALL_SOURCE_DIR}/ConfigVars
WORKING_DIRECTORY ${DYNCALL_SOURCE_DIR})

ADD_CUSTOM_TARGET(dyncall DEPENDS ${DYNCALL_LIBRARIES})
-----------------------------------------------------------

I understand that to build dyncall needs DYNCALL_LIBRARIES:
- DYNCALL_LIBRARIES depends on ConfigVars
- and ConfigVars are created with the custom command _after_ tar and after the
configure step (configure creates the ConfigVars file)

So, I don't see any clear error here. Maybe is a cmake bug ....
