You might use "cmake --build" in conjunction with a custom target:
CMAKE_MINIMUM_REQUIRED(VERSION 2.8 FATAL_ERROR)
PROJECT(PKGSRC NONE)
IF(EXISTS ${CMAKE_SOURCE_DIR}/manifest.txt)
# In packaged source tree.
FILE(COPY ${CMAKE_SOURCE_DIR}/manifest.txt
DESTINATION ${CMAKE_BINARY_DIR})
ELSE()
# In original source tree.
FILE(WRITE ${CMAKE_BINARY_DIR}/manifest.txt "...\n")
INCLUDE(CPack)
ADD_CUSTOM_TARGET(pkgsrc
COMMAND ${CMAKE_COMMAND}
-E copy ${CMAKE_BINARY_DIR}/manifest.txt
${CMAKE_SOURCE_DIR}/manifest.txt
COMMAND ${CMAKE_COMMAND}
--build ${CMAKE_BINARY_DIR}
--target package_source
COMMAND ${CMAKE_COMMAND}
-E remove ${CMAKE_SOURCE_DIR}/manifest.txt
)
ENDIF()
The pkgsrc target prepares the source tree for packaging, builds the
source package via "cmake --build" and cleans up. AFAICS, writing to
the source tree is unavoidable in order to achieve your aim, perhaps
unless you copy the whole source tree to a subdirectory of the build
tree, prepare and configure it in another subdirectory and build the
regular package_source target in there. :[
