我試圖在同一個項目中使用CMake與自己的庫一起構建一個vala應用程序。構建應用程序工作正常，所以我添加了一個新的「lib」目錄到我的項目具有以下的CMakeLists.txt：Cmake「沒有規則制定目標」，同時構建共享庫
# Configure precompile
vala_precompile (LIB_VALA_C ${LIB_NAME}
Session.vala
PACKAGES
gio-2.0
gee-0.8
OPTIONS
--thread
--vapidir=${CMAKE_SOURCE_DIR}/vapi
--target-glib 2.32
GENERATE_VAPI
${LIB_NAME}
GENERATE_HEADER
${CMAKE_PROJECT_NAME}
)
# Add executable
add_library (${LIB_NAME} SHARED ${LIB_VALA_C})
# Set library properties
set_target_properties (${LIB_NAME} PROPERTIES
OUTPUT_NAME ${LIB_NAME}
VERSION ${LIB_SOVERSION}.${LIB_VERSION}
SOVERSION ${LIB_SOVERSION}
)
target_link_libraries (${LIB_NAME} ${LIB_LIBRARIES})
# Installation
install (TARGETS ${LIB_NAME} DESTINATION ${CMAKE_INSTALL_FULL_LIBDIR}/)
install (FILES ${CMAKE_CURRENT_BINARY_DIR}/${LIB_NAME}.pc DESTINATION ${CMAKE_INSTALL_FULL_LIBDIR}/pkgconfig/)
install (FILES ${CMAKE_CURRENT_BINARY_DIR}/${LIB_NAME}.vapi DESTINATION ${CMAKE_INSTALL_FULL_DATAROOTDIR}/vala/vapi/)
install (FILES ${CMAKE_CURRENT_SOURCE_DIR}/${LIB_NAME}.deps DESTINATION ${CMAKE_INSTALL_FULL_DATAROOTDIR}/vala/vapi/)
install (FILES ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_PROJECT_NAME}.h DESTINATION ${CMAKE_INSTALL_FULL_INCLUDEDIR}/${LIB_NAME}/)
中的CMakeLists.txt在項目的根目錄包含以下內容：
# Project name
project (drop)
# Minimum requirements of build-system
cmake_minimum_required (VERSION 2.8)
cmake_policy (VERSION 2.6)
# Global configuration

set (VERSION "0.1")
set (VERSION_INFO "Release")
set (PREFIX ${CMAKE_INSTALL_PREFIX})
set (DOLLAR "$")
# Library configuration

set (LIB_SOVERSION 0)
set (LIB_NAME ${CMAKE_PROJECT_NAME}-${LIB_VERSION})

# Link the avahi library
add_definitions (-lavahi)
# Link dependencies

add_definitions (${LIB_CFLAGS})

link_directories (${DEPS_LIBRARY_DIRS})
link_directories (${LIB_LIBRARY_DIRS})
# Load directories

構建項目現在主要的應用程序仍然建立沒有問題，但是當庫的構建開始這個錯誤顯示（翻譯）：
make[2]: *** No rule to make »../lib/drop-1.0«,
required by »lib/drop-1.0«. End.
make[1]: *** [lib/CMakeFiles/drop-1.0.dir/all] Errors 2
make: *** [all] Errors 2
不好我不是塔t與CMake很相似，並沒有得到那個錯誤信息的含義，也不知道是什麼導致了它。 我已經比我與他們的CMakeLists.txt文件中說的也是內置了一個「正常」的應用程序和一個圖書館的另一個項目，但我找不到，使我的代碼不工作的區別：http://bazaar.launchpad.net/~wingpanel-devs/wingpanel/trunk/files/head:/
它如果你能給我一些我可以在CMake-Files中錯過的提示，那將是非常好的。
