Hello.
I'm using Cygwin as a shell, and MinGW as a compiler. I'm experiencing a
weird build problem with CMake.
Steps to reproduce the problem.
1. Install Cygwin with standard packages.
2. Download and unpack the following MinGW archives into C:/MinGW:
- [binutils-2.21-2-mingw32-bin.tar.lzma

e.g. with this script:
#!/bin/sh
# MinGW setup script
SRCNAM=mingw
MINGW=C:/MinGW
mkdir -p $MINGW
for file in $(ls $SRCNAM/*tar*); do
echo "Extracting $file to $MINGW";
tar -xf $file -C $MINGW
done;
cp $MINGW/bin/mingw32-make.exe $MINGW/bin/make.exe
3. Restart Cygwin shell.
4. Download
http://sourceforge.net/projects/pcre/files/pcre/8.12/pcre-8.12.tar.bz2/download
into a directory, and put the following script into the same directory:
#!/bin/sh
# MinGW build script for PCRE
SRCNAM=pcre
VERSION=8.12
MINGW=C:/MinGW
TMP=tmp
rm -rf $TMP
mkdir -p $TMP/{src,build}
tar -xf $SRCNAM-$VERSION.tar.bz2 -C $TMP/src
cd $TMP/build
# Exclude sh.exe from PATH so that CMake doesn't complain.
OLD_PATH="$PATH"
export PATH=$(echo $PATH | sed -e "s/:\/bin:/:/g" | sed -e
"s/:\/usr\/bin:/:/g")
cmake -G "MinGW Makefiles" ../src/$SRCNAM-$VERSION
# Return previous PATH value back.
export PATH="$OLD_PATH"
Run it from Cygwin shell, and see:

However, if the line in the script is changed from
mkdir -p $TMP/{src,build}
to
mkdir -p $TMP/{src,build/tmp}
i.e. tmp directory is created in the directory cmake.exe is issued, we
get correct behaviour:

I can see cmake creates some auxiliary bat files during its run. But why
do I need to create tmp directory manually? Is this OK?
Thanks.
