Bison & Flex cmake配置

Question

我有Makefile文件来管理我的bison&flex&c++项目的构建：

CFLAGS = -g
all:      cppcalc
cppcalc:    cppcalc.lex.o cppcalc.tab.o
    c++ -g -o $@ cppcalc.tab.o cppcalc.lex.o -lm
cppcalc.lex.o: cppcalc.lex.c cppcalc.tab.hh cppcalc-ctx.hh
    c++ -c $<
cppcalc.tab.o: cppcalc.tab.cc cppcalc-ctx.hh klasa.hh
cppcalc.lex.c: cppcalc.l
    flex -ocppcalc.lex.c cppcalc.l
cppcalc.tab.cc cppcalc.tab.hh: cppcalc.yy
    bison -vd cppcalc.yy

这个很好用。我想把这个想法转换成cmake。现在我在下面写了一些类似的东西，但是我在输入make之后会出错，我不知道哪里出了问题：

cmake_minimum_required(VERSION 2.8)

find_package(BISON)
find_package(FLEX)

BISON_TARGET(MyParser cppcalc.yy ${CMAKE_CURRENT_BINARY_DIR}/cppcalc.tab.cc COMPILE_FLAGS -vd)
FLEX_TARGET(MyScanner cppcalc.l  ${CMAKE_CURRENT_BINARY_DIR}/cppcalc.lex.c)
ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

 include_directories(${CMAKE_CURRENT_BINARY_DIR})
 add_executable(Foo
    ${BISON_MyParser_OUTPUTS}
    ${FLEX_MyScanner_OUTPUTS}
    cppcalc-ctx.hh
    klasa.hh
 )

Answer 1

cmake_minimum_required(VERSION 2.8)

find_package(BISON 2.4.1)
find_package(FLEX 2.5.35)

BISON_TARGET(MyParser cppcalc.yy ${CMAKE_CURRENT_BINARY_DIR}/cppcalc.tab.cpp)
FLEX_TARGET(MyScanner cppcalc.l  ${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp)
ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

include_directories(${CMAKE_CURRENT_BINARY_DIR})
include_directories(${CMAKE_CURRENT_SOURCE_DIR})
add_executable(Calc
  ${BISON_MyParser_OUTPUTS}
  ${FLEX_MyScanner_OUTPUTS}
)
