From 363825cd55595b7de62fcf610836f6156a9f1a31 Mon Sep 17 00:00:00 2001 From: Brad King Date: Thu, 30 May 2013 16:11:11 -0400 Subject: FindBoost: Fix handling of \ in input paths (#14179) In commit 5b9149e0 (FindBoost: Overhaul caching and search repeat behavior, 2012-09-24) we refactored the internal library search to use a _Boost_FIND_LIBRARY macro to wrap around find_library calls. However, CMake macros re-process escape sequences when evaluating calls inside the macro after substituting placeholders (a historical bug). In order to avoid escape sequences, convert backslashes to forward slashes before passing arguments to the _Boost_FIND_LIBRARY macro. --- Modules/FindBoost.cmake | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/Modules/FindBoost.cmake b/Modules/FindBoost.cmake index 8d8b10c..0a9ffc1 100644 --- a/Modules/FindBoost.cmake +++ b/Modules/FindBoost.cmake @@ -928,9 +928,13 @@ foreach(COMPONENT ${Boost_FIND_COMPONENTS}) message(STATUS "[ ${CMAKE_CURRENT_LIST_FILE}:${CMAKE_CURRENT_LIST_LINE} ] " "Searching for ${UPPERCOMPONENT}_LIBRARY_RELEASE: ${_boost_RELEASE_NAMES}") endif() + + # Avoid passing backslashes to _Boost_FIND_LIBRARY due to macro re-parsing. + string(REPLACE "\\" "/" _boost_LIBRARY_SEARCH_DIRS_tmp "${_boost_LIBRARY_SEARCH_DIRS}") + _Boost_FIND_LIBRARY(Boost_${UPPERCOMPONENT}_LIBRARY_RELEASE NAMES ${_boost_RELEASE_NAMES} - HINTS ${_boost_LIBRARY_SEARCH_DIRS} + HINTS ${_boost_LIBRARY_SEARCH_DIRS_tmp} NAMES_PER_DIR DOC "${_boost_docstring_release}" ) @@ -960,9 +964,13 @@ foreach(COMPONENT ${Boost_FIND_COMPONENTS}) message(STATUS "[ ${CMAKE_CURRENT_LIST_FILE}:${CMAKE_CURRENT_LIST_LINE} ] " "Searching for ${UPPERCOMPONENT}_LIBRARY_DEBUG: ${_boost_DEBUG_NAMES}") endif() + + # Avoid passing backslashes to _Boost_FIND_LIBRARY due to macro re-parsing. + string(REPLACE "\\" "/" _boost_LIBRARY_SEARCH_DIRS_tmp "${_boost_LIBRARY_SEARCH_DIRS}") + _Boost_FIND_LIBRARY(Boost_${UPPERCOMPONENT}_LIBRARY_DEBUG NAMES ${_boost_DEBUG_NAMES} - HINTS ${_boost_LIBRARY_SEARCH_DIRS} + HINTS ${_boost_LIBRARY_SEARCH_DIRS_tmp} NAMES_PER_DIR DOC "${_boost_docstring_debug}" ) -- cgit v0.12
