CMake and Latex - latex

Question

I am using the UseLATEX.cmake to compile my project documentation folder.
My project is organized as follows --
.
├── CMakeLists.txt
├── bin
├── build
├── cmake
│   ├── CMakeCompilerFlags.cmake
│   ├── CMakeDefaults.cmake
│   ├── MacroEnsureOutOfSourceBuilds.cmake
│   └── UseLATEX.cmake
├── doc
│   ├── Doc.tex
│   ├── CMakeLists.txt
│   └── images
│   ├── img1.png
│   ├── img2.png
│   ├── img3.png
│   └── img4.jpeg
............
└── src
├── CMakeLists.txt
├── file1.cpp
├── file2.cpp
└── file3.cpp
My root level cmake file is like this ...
cmake_minimum_required(VERSION 2.8 FATAL_ERROR)
# Set path for CMake
set(CMAKE_MODULE_PATH
"${CMAKE_SOURCE_DIR}/cmake"
${CMAKE_MODULE_PATH}
)
# Define project settings
project(proj)
set(APPLICATION_NAME ${PROJECT_NAME})
include(CMakeDefaults)
# Compile Program and Docs
include_directories(inc)
add_subdirectory(src)
add_subdirectory(doc)
And the CMakeList file in the document file is --
include(UseLATEX)
ADD_LATEX_DOCUMENT(Doc.tex
#BIBFILES mybib.bib
IMAGE_DIRS images
DEFAULT_PDF
)
Now I compile my project in the build folder. Is there any way I can copy back the Doc.pdf file created in the build/doc folder back to my original build folder?

Answer 1

Since ADD_LATEX_DOCUMENT adds a CMake target named pdf here, you should be able to make use of add_custom_command. Try adding the following to your /doc/CMakeLists.txt after the ADD_LATEX_DOCUMENT call:
add_custom_command(TARGET pdf POST_BUILD
COMMAND ${CMAKE_COMMAND} -E copy
${CMAKE_CURRENT_BINARY_DIR}/Doc.pdf
${CMAKE_BINARY_DIR}/Doc.pdf)
This custom command invokes the cmake executable (held in the variable ${CMAKE_COMMAND}) along with the -E copy arguments every time the pdf target is built.
